[0002] Geological surveying is a comprehensive undertaking that uses various technical means to systematically investigate and study the geological structure, mineral resources, hydrological conditions, and geomorphological features of the Earth's surface and deep interior. It aims to serve economic development, national defense, and scientific and technological advancement.

[0003] Chinese utility model patent CN220979365U discloses a drilling device for geological exploration, including a stabilizing frame. A mounting groove is formed in the middle of the top surface of the stabilizing frame. A hydraulic rod is fixedly installed on the inner wall of the mounting groove. A connecting plate is fixedly connected to the bottom of the hydraulic rod, and a transmission assembly is threadedly connected to the bottom of the connecting plate. An annular water tank is fixedly connected to one side of the top surface of the stabilizing frame. A water pump is fixedly installed inside the annular water tank. A water outlet pipe is fixedly installed at the output end of the water pump, and connecting pipes are inserted into both sides of the water outlet pipe. This drilling device for geological exploration, through the hydraulic rod and transmission assembly, allows surveyors to place the stabilizing frame in a designated working position. When the power to the hydraulic rod and servo motor is turned on, the hydraulic rod drives the servo motor to move slowly downwards, and its transmission rod drives the drill rod to drill a hole in the geology, thus facilitating drilling for surveyors.

During the drilling process, the soil around the borehole may loosen or even collapse, resulting in irregular borehole shape or complete failure. Secondly, after each sampling, additional time and effort are required to clean the soil sample from the drill bit, which will reduce the efficiency of borehole sampling. Utility Model Content

[0066] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0067] Please see Figure 1 - Figure 6 A geological exploration drilling device includes: a movable base 1; a support 2 fixedly mounted on the movable base 1; a lifting assembly 3 mounted on the support 2; a drilling assembly 4 mounted on the lifting assembly 3; an ejection assembly 5 mounted on the lifting assembly 3 and connected to the drilling assembly 4; a first motor 6 fixedly mounted on the top of the support 2; a cam 17 fixedly mounted on the output end of the first motor 6; a plug-in frame 7 fixedly mounted above the support 2; a fixed frame 8 plugged into the plug-in frame 7; two telescopic frames 9 respectively, with the two telescopic frames 9 respectively located at both ends of the fixed frame 8; and an annular pressure block 10 fixedly mounted on both telescopic frames 9.

[0068] The geological survey drilling equipment provided by this utility model, when in use, the drilling component 4 is started, and then the drilling component 4 is driven to descend by the lifting component 3, so that the drilling component 4 can drill and sample the soil. At the same time, the first motor 6 drives the cam 17 to rotate, and then the rotating cam 17 drives the fixed frame 8, so that the fixed frame 8 can move up and down stably under the action of the plug-in frame 7. Then the moving fixed frame 8 drives the telescopic frame 9 and the annular pressure block 10, so that the up and down annular pressure block 10 can compact the soil around the drilling component 4, thereby reducing the possibility of borehole collapse.

[0069] Furthermore, the telescopic frame 9 includes:

[0070] The plug-in frame 91 is fixedly installed at the end of the fixing bracket 8;

[0071] The L-shaped rod 92 is inserted into the inner side of the insertion frame 91, and the annular pressure block 10 is fixedly installed on the L-shaped rod 92.

[0072] The hand-tightening screw 93 is threaded onto the plug frame 91, and the screw end of the hand-tightening screw 93 abuts against the L-shaped rod 92.

[0073] Specifically, by manually reversing the hand-tightened screw 93 and moving its screw end away from the L-shaped rod 92, and then manually adjusting the L-shaped rod 92 inserted in the insertion frame 91 upwards or downwards, it is ensured that the annular compaction block 10 can contact the soil during the compaction process.

[0074] Furthermore, the lifting assembly 3 includes:

[0075] Two T-shaped plates 31 are provided, and the two T-shaped plates 31 are symmetrically fixedly installed on the inner bottom wall of the bracket 2;

[0076] A bidirectional lead screw 32 is positioned between two T-shaped plates 31, and both ends of the bidirectional lead screw 32 are rotatably connected to the two T-shaped plates 31 respectively.

[0077] There are two fixing blocks 33, and both fixing blocks 33 are threadedly connected to the bidirectional lead screw 32;

[0078] H-shaped bracket 35 is located below the bidirectional lead screw 32;

[0079] The connecting plate 34 is pinned to the H-shaped frame 35, and the other end of the connecting plate 34 is pinned to the fixing block 33.

[0080] The drive mechanism 36 is located above the bracket 2, and the output end of the drive mechanism 36 is connected to the bidirectional lead screw 32.

[0081] Specifically, the drive mechanism 36 drives the bidirectional lead screw 32 to rotate. Then, under the limiting cooperation of the bracket 2, the rotating bidirectional lead screw 32 can stably drive the two fixed blocks 33 connected to it to move closer to each other. After that, the moving fixed blocks 33 drive the H-shaped frame 35 to descend through the connecting plate 34, so that the drilling assembly 4 can contact the ground and perform drilling operations.

[0082] Furthermore, the drive mechanism 36 includes:

[0083] The second motor 3601 is fixedly installed on the top of the bracket 2;

[0084] The drive gear 3602 is fixedly installed at the output end of the second motor 3601;

[0085] Driven gear 3603 is fixedly installed at one end of bidirectional lead screw 32, and driven gear 3602 is meshed with driven gear 3603.

[0086] Specifically, the second motor 3601 drives the drive gear 3602 to rotate, and the rotating drive gear 3602 drives the bidirectional lead screw 32 to rotate through the driven gear 3603 that meshes with it, thereby enabling the H-shaped frame 35 to drive the drilling assembly 4 to rise and fall.

[0087] Furthermore, the drilling assembly 4 includes:

[0088] The third motor 41 is fixedly installed on the top of the H-shaped frame 35;

[0089] The connecting cylinder 42 is fixedly connected to the output end of the third motor 41;

[0090] The core drill bit 43 is fixedly installed at the bottom of the connecting cylinder 42.

[0091] Specifically, the third motor 41 drives the connecting cylinder 42 and the core drill bit 43 to rotate, thereby enabling the core drill bit 43 to drill and sample.

[0092] Furthermore, component 5 includes:

[0093] The inverted T-rod 51 is inserted into the inner side of the connecting cylinder 42 and the core drill bit 43;

[0094] Two T-shaped posts 52 are provided, and the T-shaped posts 52 pass through the strip groove on the connecting cylinder 42 and are fixedly connected to the inverted T-rod 51 by fixing screws;

[0095] An annular plate 53 is fixedly installed on the T-shaped column 52;

[0096] The telescopic mechanism 54 is mounted on the H-shaped frame 35, and the output end of the telescopic mechanism 54 is inserted into the annular plate 53.

[0097] Specifically, the telescopic mechanism 54 presses the annular plate 53, which then drives the T-shaped column 52, thereby allowing the inverted T-bar 51 to descend and push the soil out of the drilling assembly 4. This makes it convenient for people to collect soil samples, eliminates the need to spend extra time and effort to clean the drilling assembly 4, and improves the efficiency of drilling and sampling.

[0098] Furthermore, the telescopic mechanism 54 includes:

[0099] The first electric telescopic pole 5401 is fixedly installed on the H-shaped frame 35;

[0100] Strip plate 5402 is fixedly installed on the bottom wall of the first electric telescopic rod 5401;

[0101] The U-shaped frame is fixedly installed on one side of the strip plate 5402, and the strip plate 5402 is inserted into the outside of the annular plate 53.

[0102] Specifically, the first electric telescopic rod 5401 extends and drives the strip plate 5402, which in turn drives the U-shaped frame, thereby enabling the U-shaped frame to press down the annular plate 53. This ensures that the rotation of the drilling assembly 4 is not affected, and that the inverted T-rod 51 can push the soil out of the core drill bit 43.

[0103] Furthermore, a rectangular groove is provided on the fixed frame 8, and a roller 13 is provided on the inner side of the rectangular groove. The roller 13 is pin-connected to the fixed frame 8, and the outer wall of the roller 13 is in contact with the cam 17.

[0104] Specifically, the roller 13 can reduce the friction between the cam 17 and the fixed frame 8, ensuring that the rotating cam 17 can stably lift the fixed frame 8 for raising and lowering. Example

[0105] Based on Embodiment 1, in this embodiment: two second electric telescopic rods 14 are symmetrically and fixedly installed through the movable seat 1, and a rectangular plate 15 is fixedly installed at the bottom of each of the two second electric telescopic rods 14. Multiple fixed cones 16 are fixedly installed at the bottom of the rectangular plate 15.

[0106] The technical solution provided in this embodiment is as follows: the rectangular plate 15 is driven to descend by the extended second electric telescopic rod 14. When the rectangular plate 15 descends and contacts the ground, the fixed cone 16 below the rectangular plate 15 will be inserted into the soil, so that the movable seat 1 will not be displaced during drilling and compaction operations. Example
